Ruby Hayes spends her days working in a coffee shop and attending college. After a mysterious phone call, her ex-boyfriend Kenny goes missing and Ruby is determined to find out what happened to him. Although the police are looking into his disappearance, Ruby decides to pursue her own investigation. Details, seemingly unconnected to Kenny, begin to emerge. A body fished from the river. A vampire-themed nightclub. A shadowy group whose members include the elite and powerful of the city. Secret gatherings where perverted desires are sated and dark fantasies played out. A series of unsolved murders.

Each clue brings Ruby closer to the truth...and nearer to danger. Will she find Kenny? Or will she herself become prey?
